How long can they las.......

As the Ich, Oodinium, Brooklynlia life cycle. How long can it last in our tank in each stage at 32-33 c' ?
From my experiences... the new arrive fish without QT processing when I bring up the temp to 30-32 c' Ich would be suddenly appeared. Mostly happened with butterfly.... then I just guess that after the new comming fish if I put them in QT tank with 31-33 c' ( To speed up the ich to the free swimming stage) then it were killed in will this stage by some kind of medicine. such as KENT or Quick Cure.... Can I do like this?

Those tempuratures will not kill the parasites as you seem to already know but it can kill the fish. At the very least you are altering the pH of the fishs blood which lowers the immune system response greatly and risks hypoxia through lowered O2 levels. Never increase the temp in order to aid in parasite remedies.

Quick cure and RxP are not going to solve your problems nor will temp manipulation. I truely understand your desire for a quick convenient end to the problem but the simple fact is, there are none. You really need to set up a proper Qt where these fish can undergo proper treatments with effective remedies. If space or time is an issue at the moment, you should really consider waiting until it can be done properly and eliminate losses.

Cryptocaryon irritans + hyposalinity
Amyloodinium ocellatum + copper
If unsure of either of the above use copper

Brooklynella hostilis + formalin dips.

These are the tried and true remedies for such conditions and none can be done effectively in a display system.

Cheers

The time effect on Ich is a carry-over from freshwater Ich Ichthyophthirius multifilis. In the case of Freshwater Ich, temperature not on sped up its cycle, but could actually kill the parasite. Not so in Marine Ich. Cryptocaryon irritans is not all that much affected by higher temperatures and in fact has a viable/living/comfortable temperature range of below 50F and above the temperatures that would kill most marine fishes.

Studies performed by Dr. Burgess at 25C showed that some of the 'cyst' stage of Marine Ich can last up to 6 weeks before moving on to the Theront stage. Even though averages are given for each stage, the truth of the matter is that there is a chance that Marine Ich can live in a fishless aquarium for more than 6 weeks. It is becaue of this study and information that I advise leaving aquariums go fishless for no less than 8 weeks when it is known to have contained Marine Ich.

I'm glad to see Steve promoting the traditional cure/treatments. The reef safe and alternative treatments have never given consistently positive results.
